Adding UILabel programmatically only by code. Sizing ? (Swift)

Question

I try to add a UILabel by code which works, but not as intended.

With following Code I can see the label but the height of the label is not correct as you can see in the attached screen. I would like the uilabel sized so the height of the label corresponde to the fontsize.

Of course I could simply oversize the UILabels high so the text would fit. But I don't think thats best practice.

How do I size an UILabel based on a fontsize ?

var uilabel1=UILabel();
uilabel1.frame=CGRectMake(0, drawy, screenwidth, ititlesize);
uilabel1.text=sTextViewOptionsTitle;
uilabel1.font = UIFont(name: uilabel1.font.fontName, size: 28);
self.view.addSubview(uilabel1);
var lastelementheigth=uilabel1.frame.height;

UPDATE Solution with sizeToFit()

Thanks for the answer regarding sizeToFit(). This did the trick with some additional code to position the control. updated Code:

  var uilabel2=UILabel();
    //uilabel2.frame=CGRectMake(0, drawy, screenwidth/2, DropdownHeigth);
    uilabel2.text=sTextSizeTextViewer;
    uilabel2.font = UIFont(name: uilabel2.font.fontName, size: iFontsize_Option);
    uilabel2.sizeToFit();
    uilabel2.frame.origin = CGPoint(x: 0, y: drawy);

    self.view.addSubview(uilabel2);
    lastelementheigth=uilabel2.frame.height;

Thanks a lot that did the trick ! I updated my question with updated code. — mcfly soft

You may only need to call -sizeToFit. This will change the label's size to its "preferred" size based on its contents. Then you can reposition the origin or center if desired.
